TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that we, CHARLES W. BLISS and OLIVER M. ADAMS, of Milford, in the county of Worcester, and State of Massachusetts, have invented a new and useful Boot-Shank Laster; anddo hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, ofi

which- A f Figure 1 is a top view,

Figure 2 a side elevation, and

Figure 3 a vertical section of it. i

In such drawings, A denotes a cam or round block of' wood er metal, having a handle, B, extended froru'ts periphery. The said cam has a socket, a, made within it and parallel to its opposite sides, and opening out oi'` the periphery of the cam, in manner as represented. Within the socket there is placed the shank b of a cla\v,.

C, formed as shown in the drawings This shank turns freely on a pin, c, which goes through it and the cam."l

. In using the implement, the circumference or the cam is to be placed against one portion of the shank` of the upper of a boot when on a last, the claw being extended across the shank Kand int'o the other part'oi' the;

l shank of theupper. By turning the cam by means of the handle the earn will adjust itself to the shoeor last,

and the claw will draw the shank part of4 the upperclosely down upon the last, so as to enable such part of the upper to be tacked down to the insole preparatory to being stitched or pegged thereto. This little and simple toolwe have found very useful and effective for the purpose for which it is intended. i

We claim as our inventionl p The said boot-shank laster, cornposed ofthe cam A, the handle B, and the shanked claw C, arranged andv applied together as specified. p

OLIVER M. ADAMS.
